Be it known that l, Anonrr-r C. Rnorrnn, a citizen of the United States, residing at )akville, in the county of Litchlield and fi'itatc of Connecticut, have invented a new and useful improvement in Shade-Supports for incandescent Electric Lamp Sockets; and I do hereby declare the following, when ta on in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in r Figure 1, a broken view partly in elevation and partly in sectionof a shadesupport embodying my invention, shown as in use;

My invention relates to an improvement in shade-supports of the type in which the shade-mounting means and the lampqnounting means are rigidly connected by two, bdwed wire frame-arms. Heretofore, the lamp-ends of these arms have been fastened to lamp-mounting means in the form 01" a clamping-ring adapted to be spread open to receive a standard lamp-socket and provided with a set screw by means of which the ring has been clamped thereupon, while the opposite or shade-ends of the arms have. been fastened to shade-mounting means of various forms. The object of my present invention is to simplify and improve the convenience and appearance of shade-supports of the type described.

With these ends in v1ew, my nvention consists in a shade-support comprising two, bowed wire frame-arms, shade-mounting means secured to the said arms at the shade- Specification of Letters Patent.

ends thereof, and lamp-mounting means fastened to the lamp-endsof the said arms In carrying out my invention, as herein shown, the two bowed frame-arms 3, 3 of my improved fixture have their lamp-ends, so to speak, straightened, flattened, and perforated for being secured by rivets 4 to a lamp-receiving ring 5 having its outer end formed with a bead 6 and its inner end threaded, as at 7, the said ring 5 being adapted to receive the threaded lampreceiving end 8 of a standard incandescent electric-lamp socket 9, the threads of the said ring and socket corresponding in pitch, and the socket being formed with an abutment shoulder '10, though this latter may be omitted, in which case the bead 6 of the ring 5 would abut against the annular shoulder 11 between the two ends of the lampsocket.

The shade-mounting means applied to the opposite or shade-ends of the two framearms 3, may assume a variety of forms. As shown, the shade-mounting means consists of a mounting-shell 12 secured in place by a removable, internally threaded binding-knob 13 applied to a screw 14, the headed inner end of which is mounted in a sheet-metal spider or union 15 having four, transversely arranged arms, of which the arms 16, 16 are clasped over the inwardly bent shade-ends of the arms 3, while the arms 17 17 are clasped over the inner portion of a shadesupporting cross-piece 18 arranged at a right angle to the ends of the arms 3, whereby I form a four-point bearing, as it were, for the shade which is held against the four points of this bearing by means of the mounting-shell 12, which in turn is held in place by the binding-knob 13 on the screw 14. But, as explained, I do not limit myself to employing such shade-mounting means in conjunction with my improved lampmounting means. It will be noted that the lamp-receiving ring 5 is a onepiece ring and provided with continuous threads and is thus adapted to be directly appliedto the threaded lamp-receiving end 8 of a standard incandescent electric lamp-socket. No additional clamping means of any description Patented July 5, 1921.

are required to adapt the fixture to be used in an inverted position, as shown, or in an upright position, in which the shade is reversed. In the inverted position, as for indirect lighting, the entire weight of the shade and the parts forming the shade-support fall upon the lamp-receiving ring 5,-

which, on account of being screwed directly upon the socket is amply strong sustaining the weight and will not work loose.

I claim:

In a shade-support for threaded incandescent-lamp sockets, the combination with two bowed frame arms, shade mounting means fastened to the shade-ends of the said arms, and lamp-socket mounting-means permanently fastened to thelarnp-ends of the said arms and consisting of a one-piece lampsocket receivingd'ing fastened to the lampends of the said arms, and formed at its inner end with threads for direct coaction with the threads at the larnp-receiving end of the lamp-socket, whereby, by the use of the said single ring, the said support and lamp-socket may be solidly screwed together for the use of the said support, either in the upri 'ht or in the inverted position.

In testimony whereof I have signed this specification in the presence of two sub scribing witnesses.
